JP4152293B2 - Information provision system using code information - Google Patents

Description

  The present invention relates to an information providing system using code information.

  With the development of communication technology and network technology, and the advancement of computer technology, the Internet, which is a representative interactive media, is going to shift from narrowband to broadband.

  In Japan, with the addition of Internet functions to mobile phones, there are overwhelmingly more Internet users on mobile phones (so-called browser phone users) than Internet users centering on European and American personal computers.

Many users using such browser phones enjoy e-mails on mobile phones or access web pages compatible with browser phones to obtain information.
As for the browser phone, for example, in Japanese Patent Application Laid-Open No. H10-260260, a web site using a browser phone can be used without a new WEB area hosting service contract, and even without a PC environment, construction software, or knowledge. It provides mobile phone system technology that can be easily constructed. This is because the HP creation auxiliary server has a function of providing an HP creation screen for access from the browser phone, building an HP directory file based on information input from the HP creation screen, and uploading it to the WEB server. The server is provided with a function of receiving an upload from the HP creation auxiliary server and posting the HP directory file in the WEB area for the browser phone.

  By the way, the web address of the content provider is registered in the official menu of the service of the carrier by the authorization of the mobile phone company (so-called carrier). In this case, it is possible to access the web page by accessing the specific content along the menu registered by the carrier.

  However, to register for a career, there is a fairly high hurdle review and not everyone is registered. Therefore, a content provider who is not registered transmits information using a unique URL. This is called a so-called site.

On the other hand, in the case of a browser phone user, when such a content provider uses a unique URL, it is accessed by keying in the URL or by selecting a URL attached to an e-mail (web). to)).
JP2003-122675A

  However, such URL input and selection is complicated. Therefore, as a method for easily accessing information to more browserphone users, there is, for example, number code access using telephone toll-free. This is a method in which Internet address information is converted into specific numerical information, and an Internet number, a Chinese character URL, or the like is used. However, in this method, the number that can be used does not necessarily match the number and kanji of the person who wants to use, and it is considered that there is still room for improvement in this sense.

  The problem to be solved is that the input and selection of the URL is complicated, and the invitation to interactive media cannot be realized easily and reliably.

(First embodiment)
FIG. 1 is a diagram showing a first embodiment of an information providing system using code information of the present invention, and FIG. 2 is a diagram for explaining an information providing method in the information providing system using code information of FIG. It is a flowchart.

  The information providing system using the code information shown in FIG. 1 includes a code issuing server system 10, an advertiser server system 20, and a mobile phone 30. The code issuing server system 10, the advertiser server system 20, and the mobile phone 30 can communicate with each other via the Internet 40 as a network. Here, the network is not limited to the Internet 40 but may be a dedicated line or the like.

  The code issue server system 10 issues, for example, two-dimensional code information as code information in response to a request from an advertiser, and includes a code issue management server 11. The code issuance management server 11 manages the two-dimensional code information issued in response to a request from the advertiser and also decodes the two-dimensional code information used on the mobile phone 30 side. Is provided.

  The advertiser server system 20 as the information providing server system manages the two-dimensional code information issued by the code issuing server system 10 and includes an advertiser server 21. The advertiser server 21 provides various types of information in response to access using the two-dimensional code information from the mobile phone 30.

  Here, the issued two-dimensional code information can be printed and distributed on a distribution, for example. The distribution includes newspapers, magazines, advertisements, company brochures, flyers, OOH (Out Of Home) media, POPs, tickets, tickets, business cards, tags, and the like.

  By printing the two-dimensional code information on these distributions, it is possible not only to guide the mobile phone 30 to the advertising campaign site, but also to make various ticket reservations and settlements (or settlements), product sales and settlements. (Or settlement) service, TV program reservation service, development in B2B business, etc. can be realized.

  In addition, by printing the two-dimensional code information on the distribution in this way, as described above, it is not necessary to register the web address by the certification of the mobile phone company (so-called carrier). It provides an environment in which companies can easily participate and are encouraged to create new businesses. In other words, there are two types of services that are currently provided by carriers: official sites and unofficial sites (so-called selfish sites). There is no problem if all contents and services are supposed to be official websites, but it is difficult to authenticate the carrier side and time is required, so it is difficult to make everything official.

  By the way, the dial service Q2, which is a paid service provided by a telephone company, is also a service development that bundles content holders and service destinations. This is because the communication line of the telephone company is not used without permission. For this reason, services that are not good by the telephone company (customs) can be interrupted without permission from the telephone company.

  On the other hand, the Internet does not do such a thing, and the web site is judged by a free transaction between the caller and the user. In this case, it is assumed that the user enjoys the service while making a certain judgment, and one of the methods is based on cooperation with the paper media, and service information is obtained from the paper media and jumped to the service site. It will be judged whether or not. Since these services are not controlled by the carrier and are operated by a trust relationship between the caller and the user, as a result, companies of any business type can participate.

  For browser phone users who use the mobile phone 30, access by inputting a URL, access by selecting a URL given to an e-mail (web to), information replaced with a number or kanji Access by entering a specific page is also unnecessary.

  A mobile phone 30 as a mobile terminal has a photographing function using a camera equipped with a CCD as an image pickup device, and includes a CCD reading unit 31, a decoding unit 32, a browser phone function unit 33, and a storage unit. 34 and a control unit 35 are provided.

  The CCD reading unit 31 reads image information taken by a CCD camera. Here, the image information may be either a still image or a moving image as long as it can be captured by the image sensor. In the present embodiment, for example, a QR code 51 as two-dimensional code information printed on a printed matter 50 such as a magazine is extracted and read. The QR code 51 read by the CCD reading unit 31 is temporarily stored in the storage unit 34.

  The decoding unit 32 decodes the QR code 51 read by the CCD reading unit 31. When decoding the QR code 51, a JAVA (registered trademark) application which is decoding software is used. This JAVA (registered trademark) application can be downloaded by accessing the code issue management server 11. The downloaded JAVA (registered trademark) application is stored in the storage unit 34.

  The browser phone function unit 33 as a browsing function unit accesses the web page based on the web address decoded by the decoding unit 32 in accordance with a predetermined control program, and receives detailed information from the access destination in a packet, for example. The detailed information is displayed on the screen of the mobile phone 30. The browser phone function unit 33 is adapted to download a JAVA (registered trademark) application.

  The storage unit 34 stores a QR code 51 read by the CCD reading unit 31, a downloaded JAVA (registered trademark) application, and the like. The control unit 35 controls the operation of each unit according to a predetermined control program.

  Next, an information providing method in the information providing system using the two-dimensional code information having such a configuration will be described.

  First, as shown in FIG. 2, for example, when a QR code 51 as two-dimensional code information printed on a printed matter 50 such as a magazine is photographed by the CCD camera of the mobile phone 30 (step 201), the CCD reading unit The photographed QR code 51 is read by 31 (step 202).

  The QR code 51 read by the CCD reading unit 31 is temporarily stored in the storage unit 34 (step 203). When the QR code 51 is stored in the storage unit 34, the decoding unit 32 decodes the QR code 51. At this time, the decoding of the QR code 51 is executed by calling a JAVA (registered trademark) application that is decoding software for decoding the QR code 51 from the storage unit 34. If it is determined that the JAVA (registered trademark) application is not stored in 34 (step 204), the browser phone function unit 33 accesses the code issuance management server 11 according to an instruction from the control unit 35. The trademark application is downloaded (step 205). The downloaded JAVA (registered trademark) application is stored in the storage unit 34 (step 206).

  When the JAVA (registered trademark) application is thus obtained, the QR code 51 is decoded by the decoding unit 32 (step 207). At this time, since the web address is obtained by decoding the QR code 51 (step 208), the browser phone function unit 33 accesses the web page based on the web address (step 209). When the detailed information from the access destination is received, for example, in a packet (step 210), the detailed information is displayed on the screen of the mobile phone 30 (step 211).

  Thus, in the first embodiment, the code issuing server system 10 issues the two-dimensional code information in response to a request via the Internet 40, and the advertiser server system 20 issues the two-dimensional code. The two-dimensional code information is received via the Internet 40, and the received two-dimensional code information is managed by the advertiser server 21, and the two-dimensional code is received by the mobile phone 30 having a photographing function using a CCD camera. The information is photographed, the web address included in the photographed two-dimensional code information is obtained, the web page is accessed via the Internet 40 using the obtained web address, and the advertiser server system 20 In response to access from the mobile phone 30, information is transferred to the mobile phone 30 via the Internet It was to be provided through.

  Thus, as in the past, the content provider 2 issued by the code issuing server system 10 even if its web address is not registered in the menu of the service of the carrier by the certification of the mobile phone company (so-called carrier). Dimension code information can be printed and distributed on the above-mentioned advertisements, company brochures, insert flyers, OOH media, POPs, tickets, tickets, business cards, tags, etc. Inviting to interactive media can be realized easily.

  On the other hand, many browser phone users who use the mobile phone 30 capture the two-dimensional code information printed on the distribution with a CCD camera mounted on the mobile phone 30 to obtain a desired web page. Since access can be performed, it is not necessary to input a unique URL of the content provider as in the conventional case, and access to the interactive media can be executed very easily and reliably.

(Second Embodiment)
FIG. 3 is a diagram showing a second embodiment in which the configuration of the information providing system using the code information of FIG. 1 is changed, and FIGS. 4 to 5 are operations of the information providing system using the code information of FIG. It is a figure for demonstrating. Note that, in the drawings described below, the same reference numerals are given to portions common to those in FIG. 1, and duplicate descriptions are omitted.

  In the information providing system using the two-dimensional code information shown in FIG. 3, for example, the advertiser server system 20 includes a public key management server 22 and a secret key management server 23.

  The public key management server 22 manages a public key for decoding, for example, an encrypted part of the QR code 51 as two-dimensional code information, and the public key will be described later. The secret key management server 23 manages a secret key used when generating an encrypted part of the QR code 51 issued on the code issuing server system 10 side.

  Here, the QR code 51 issued on the code issuing server system 10 side has a public part and an encrypted part, for example, as shown in FIG. The public part of the QR code 51 includes public information such as the own IP address on the advertiser server system 20 side, for example. The encrypted portion of the QR code 51 includes necessary information such as an encrypted web address. When generating the encrypted portion of the QR code 51, the above-described secret key is used. Note that the encrypted portion of the QR code 51 may have tag information such as CGI (Common Gateway Interface). In this case, the advertiser server system 20 can perform processing in response to a request from the web, and can provide information on the processing to the mobile phone 30 side.

  Here, the URL information that the user wants to jump to is encoded into the QR code 51 after being converted into a number sequence. Two types of information are converted as information for converting URL information. One is the service destination management IP address of the public part. The other is necessary information of the encrypted part. Specifically, “when a certain distribution destination is carrying out mobile EC service on its own site with its own content”, a service destination management IP address (published portion: 23476987) that accumulates information on this service, The address of the mobile EC site that provides the service is “www.m-service.com/mec/index.thml”. In this example, the service destination management IP address “23447687” and the CGI tag information are decoded in the mobile phone 30 from the QR code information.

  Next, jump to the service destination management IP address “23447687”. Here, the private key is received and obtained, the address “www.m-service.com/mec/index.thml” of the mobile EC site that is providing the service is obtained, and the service is jumped to.

  Next, an information providing method in the information providing system using the two-dimensional code information having such a configuration will be described.

  First, as shown in FIG. 5, for example, when the QR code 51 is issued on the code issuing server system 10 side in response to a request from an advertiser, a secret key is received from the secret key management server 23 (step 501). . By using this secret key, an encrypted part obtained by encrypting a part of the character string of the QR code 51 is generated (step 502). By generating the encrypted part, a QR code 51 having a public part and an encrypted part is issued (step 503). The issued QR code 51 is printed on a printed matter 50 such as a magazine and widely distributed.

  On the other hand, when the QR code 51 printed on the printed matter 50 such as a magazine is photographed by the CCD camera of the mobile phone 30 (step 504), the photographed QR code 51 is read by the CCD reading unit 31 (step 504). 505). The QR code 51 read by the CCD reading unit 31 is temporarily stored in the storage unit 34 (step 506). When the QR code 51 is stored in the storage unit 34, the decoding unit 32 decodes the QR code 51. At this time, the JAVA (registered trademark) application, which is decoding software for decoding the QR code 51 from the storage unit 34, is called to execute the decoding of the QR code 51, but the JAVA (registered) is stored in the storage unit 34. If the (trademark) application is not stored (step 507), as described above, the JAVA (registered trademark) application is downloaded by accessing the code issuance management server 11 (step 508). The downloaded JAVA (registered trademark) application is stored in the storage unit 34 (step 509).

  When the JAVA (registered trademark) application is thus obtained, the public part of the QR code 51 is decoded by the decoding unit 32 (step 510). At this time, since the own IP address on the side of the advertiser server system 20 shown in FIG. 4, for example, is obtained by decoding the QR code 51 (step 511), the browser phone function unit 33 uses the electronic address based on the IP address. Transmission by mail is performed (step 512).

  At this time, in response to the response from the secret key management server 23 of the advertiser server system 20, an e-mail attached with the secret key is returned to the accessed mobile phone 30 (step 513).

  When the mobile phone 30 receives the secret key, the encrypted part of the QR code 51 shown in FIG. 4 is decoded by the JAVA (registered trademark) application stored in the storage unit 34 (step 514). Here, when the web address is obtained by decoding from the encrypted part (step 515), the browser phone function unit 33 accesses the web page based on the web address (step 516). When the detailed information from the access destination is received, for example, in a packet (step 517), the detailed information is displayed on the screen of the mobile phone 30 (step 518).

  As described above, in the second embodiment, the public part and the encrypted part are provided in the two-dimensional code information, and decoding of the encrypted part is performed on the side of the advertiser server system 20 that requested the issue of the two-dimensional code information. Since the private key obtained from the private key management server 23 is provided, various information from the advertiser server system 20 is reliably provided to the mobile phone 30 that has been accessed based on the IP address of the public part. Is called.

  In addition, since various types of information are provided only to the mobile phone 30 that has been accessed, it is easy to manage the mobile phone 30 that has been accessed, and it is easy to build security, and unauthorized use. Elimination can also be realized easily.

  In the second embodiment, the description has been given of the case where the decryption of the encrypted part on the mobile phone 30 side is performed by the secret key obtained from the secret key management server 23. However, the present invention is not limited to this example. When transmission by e-mail based on the IP address is performed from the mobile phone 30 side, the encrypted part is attached to the e-mail, and the encrypted part is decoded from the secret key management server 23. Information can be returned to the mobile phone 30 side.

  In the second embodiment, the case where the web address is described in the encrypted part of the two-dimensional code information has been described. However, the present invention is not limited to this example, and the encrypted part includes cgi, SSI, ASP, and the like. The tag of can also be described. In this case, it is possible not only to expand the variety of information provided from the advertiser server system 20 by using these tags, but also to facilitate participation by companies of any business type and encourage the creation of new businesses. An easy environment can be provided.

  Further, in the second embodiment, for example, the expiration date of the code itself can be set by setting the secret key validity date / time information in the secret key management server 23, so that it is posted on the back number of the magazine, for example. It is also possible to easily limit the validity period for access from code information, as well as access to applications for prizes. Also, if code information associated with content that is offensive to public order and morals has been released, or code information that has been issued in some form of unauthorized procedure has been released, the secret key corresponding to that information Can be prevented by making the private key management server 23 unsupported or discarded. In each of the above embodiments, the case where the two-dimensional code information is a QR code has been described. However, the present invention is not limited to this example, and other codes having information in the two-dimensional directions of the horizontal and vertical directions may be used. it can.

  Further, in each of the above embodiments, the case where the two-dimensional code information is photographed by the mobile phone 30 having the photographing function using the CCD camera has been described. However, the present invention is not limited to this example. As described above, the mobile phone 30 can be provided with a function of decoding code information wirelessly. In this case, it is not necessary to mount a CCD camera on the mobile phone 30.

  In each of the embodiments described above, the case where the single QR code 51 is used as the two-dimensional code information has been described. However, the present invention is not limited to this example, and as shown in FIG. Can be added.

  That is, as shown in FIG. 6A, bitmap information can be added as an icon 51a for explaining the contents of the application. In this case, information such as the Web address and the mail address which are the contents of the QR code 51 is read into the mobile phone 30 and the bitmap information is also read. When referring to the content information of the QR code 51 on the operation screen of the mobile phone 30, the bitmap information of the read icon 51a can be displayed together so that the content can be visually shown. it can.

  Further, as shown in FIG. 6B, bitmap information can be added as a rectangular image 51b. Further, the rectangular image 51b shows a consortium of company A and company B. In this case, the shape of the rectangular image 51b can be used as an authentication key, and access to the consortiums of Company A and Company B is prevented unless the shape of the rectangular image 51b is specified. Can be effective in terms of security.

  Also, as shown in FIG. 6C, bitmap information can be added as an application switching image 51c. That is, by switching the application switching image 51c to, for example, a memo paper icon, a business card icon, an inventory icon, or the like, an application such as memo information software, business card information software, inventory software, or the like activated by the QR code 51 is switched. be able to.

  As the bitmap information, another barcode 51d can be added as shown in FIG. Separately from the QR code 51, the information of the barcode 51d can be read, and the operation of the application after reading the QR code 51 can be changed based on this information. For example, the confirmation sound when the QR code 51 is read can be changed. The barcode 51d may be a QR code.

  Also, as shown in FIG. 6E, bitmap information can be added as an extended QR code 51e. In this case, information about the advertisement itself can be given to the QR code 51, and information about the printed matter on which the advertisement has been placed can be given to the extended QR code 51e. Thus, by dividing the information into the QR code 51 and the extended QR code 51e, the reading speed of the QR code 51 or the extended QR code 51e can be increased even when the amount of information is large. It becomes.

  Further, as shown in FIG. 7, the function of each bitmap information can be switched by changing the color of the rectangular line 51f surrounding the QR code 51. In addition, the area of the bitmap information related to the QR code 51 is clearly indicated by a graphic 51f such as a rectangular line surrounding the QR code 51 or arranged around the QR code 51, and the color and / or shape of the graphic 51f. It is also possible to switch the function of each bitmap information by changing.

  A specific example of providing information in this embodiment is, for example, “music preview service using a mobile phone”. This is because when the QR code 51 printed next to the new music information introduced in the music section of the town information magazine is shot with the mobile phone 30, the shot QR code 51 is decoded within the mobile phone 30, for example, service access The number “45984521” is acquired, the information providing server “45984521” is accessed, the secret key is received, and the music preview service destination is accessed. When the music trial listening service is accessed, the music that the user wishes to listen to flows from the server to the mobile phone 30.

  For example, there is a “ticket purchase service using mobile commerce”. For example, when a QR code 51 printed in an advertisement is booked with the mobile phone 30 in order to reserve a theater ticket introduced in an advertisement section of a newspaper, the shot QR code 51 is decoded within the mobile phone 30. For example, the service access number “12345678” is obtained, the information providing server “12345678” is accessed, the secret key is received, and the ticket reservation service destination is accessed. Further, when accessing the ticket reservation service, the desired ticket reservation can be made by the mobile phone 30 by inputting desired date information and the like.

  In each of the above embodiments, the case where the decoding unit 32 on the mobile phone 30 side decodes the QR code 51 has been described. However, the present invention is not limited to this example. For example, it is also possible to receive the information of the QR code 51 transmitted to the code issuing server system 10 and decoded on the code issuing server system 10 side. In this case, the decoding unit 32 is not required on the mobile phone 30 side.

  The present invention is also applicable to small portable terminals such as PDAs.
